FOSRENOL (lanthanum carbonate)

Trial Activity: Declining
Renal Approved 2004-10-26

Fosrenol helps patients with end-stage renal disease manage high levels of phosphate in their blood. It is used as part of a broader management plan that typically includes dietary changes and dialysis. By lowering serum phosphate and calcium phosphate levels, this medication helps address a common complication of advanced kidney failure.

How FOSRENOL Works

This medication works by binding to phosphate in the digestive tract to form insoluble complexes. These complexes pass through the body without being absorbed, which prevents dietary phosphate from entering the bloodstream. This process effectively lowers both serum phosphate and calcium phosphate levels.

How We Calculate These Metrics

Trial Activity Stage

Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.

Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.

  • Growth: High proportion of early-phase trials (Phase 1/2), active development
  • Expansion: Significant Phase 3 activity, approaching or pursuing approvals
  • Mature: Substantial Phase 4 post-marketing studies
  • Stable: Mixed phase distribution, steady development
  • Declining: Low active trial ratio, reduced R&D investment
